• The GRINS foundation aims at implementating a Data platform for the transfer of knowledge and statistical analysis (AMELIA)

• Prime matter of the platform: the data lake

  • Broad repository hosting several categories of administrative data from different sources
  • Available to either private, corporate or academiic users
  • Data organised at the territorial level of municipalities (LAU/NUTS-4)

• The present R package is intended as a one of the several contributions to the data lake

• This R package covers the dimension of public education, with special regards to the territorial structure of the education system.

• Main utility: analysing territorial disparities in education quality and school infrastructure endowment

• Directly supports areal modelling

• Accessibility: All data must be publicly accessible and easy to handle for the generic user
  • Input data are open and come from publicly accessible web pages
• Updating: All information is retrieved in real time in order to be up-to date
  • Inputs are scraped from the web rather than stored in a built-in repository
• Portability: All objects should be easy to export and process with different softwares:
  • We work in the framework, and all outputs are structured as tibbles

• Get_: input data scraping. Information is not altered and the user receives a data set as close as possible as the provider releases it

• Util_: utilities; mainly data modification and editing

• Group_: data aggregation at the relevant territorial level

  • NUTS-3/Province
  • LAU/Municipality

• Map_: displaying

  • Static maps (vector format): easy to export
  • Interactive maps: preserve information on different variables

• Data from the Ministry of Education
  • Includes:
    • National Schools Registry
    • School Buildings database
    • Students and teachers counts
  • Mainly available at the school level (except for the count of teachers)
• Ultra - Broadband implementation
  • Available at the school level
• Invalsi census survey
  • Available at the NUTS-3 / LAU level

• Schools ID - mechanographical codes
  • Most complete list: National Schools Registry
  • Identifies both school order and address (of high schools)
• School buildings ID - typically numeric codes
  • Only included in the School buildings DB

• Main source of information regarding the school infrastructure

• Mostly includes categorical variables, regarding several aspects such as:

  • Environmental context
  • Reachability by public or private transport
  • Building period
  • Surfaces and volumes

• As an example, in the next slides we display middle schools area surface (on logarithmic scale to ease the comparison) for the three regions of Apulia, Basilicata and Calabria.

Input_DB23_MIUR <- Get_DB_MIUR(Year = 2023, 
                               input_Registry = Registry23) 
## ## 2022/23 is the latest year available
#à ## then, remember adding message = FALSE

DB23_MIUR_mun <-  Group_DB_MIUR(Input_DB23_MIUR, InnerAreas = FALSE
                                )$Municipality_data %>% 
  dplyr::mutate(log_Surface = log(.data$School_area_surface))

head(DB23_MIUR_mun)

DB23_MIUR_mun %>% 
  Map_School_Buildings(input_shp = Mun22_shp, field = "log_Surface", 
                       level = "LAU", order = "Middle",
                       region_code = c(16, 17, 18), verbose = FALSE)
